2 Claims. (Cl. 210-6) This invention relates to a sewage treating is anopening 6 in which a plug 1 has been posiapparatus of the kind commonlyknown as tioned. Positioned in the plug 1 and extending septic tanks andin which the heavier and lighter therethrough there is a. verticalsuction tube 8 parts of the sewage are separated and undergo whichterminates at its lower end in a circular certain changes due tobacteriological action cone shaped suction member 9 which is in turn 5within the tank. positioned upon the bottom of the tank I at a Theprincipal object of this invention is the slight distance therefrom bymeans of a plurality provision of a septic tank which is so constructedof legs Ill. The circular cone shaped suction that the capacity of thetank may be utilized member 9 being of slightly smaller diameter than 0to the best advantage for the settling of the sewthe inside of the tankI so as to permit the 10 age in that a relatively large settling area isnatural accumulation of sludge to pass between provided and is equippedwith a practical means the inside walls of the tank I and the edges offor removing natural accumulation of sludge the circular cone shapedsuction member 9. without otherwise disturbing the contents of theTelescopically positioned upon the upper end of tank or requiring thatthe tank be opened. the vertical suction pipe 8 there is a secondary 15It is well known that after a septic tank has vertical suction pipe Hwhich is of a suflicient been in use over a period of years aconsiderable length to reach to the surface or the ground l2accumulation of sludge is formed in thebottom and is provided at thispoint with a suitable cap of the tank and that if this sludge is notremoved l3 which may or may not be provided with vent it will seriouslyaffect the eflicient action of the holes as desired; 20 tank and resultin an unsanitary, undesirable In order that the sewage flowing into thetank condition.

A pair of similar 5 destruction of the lawn or shrubs underwhich baffles l5 are providedat the opposite side of the tank may beburied. In my invention I the tank I and adjacent to the outlet opening3. have provided a septic tank so designed that the Itwill be seen thatI have provided a simple S d e may be removed from time to time withandextremely practical form of septic tank 0 out digging up the tank or inany way disturbcombined with a positive means for removing ing t lawnShrubs disturbing the liquid the sludge therefrom in that it is onlynecescontents of the tank itself. This desirable feasary to attach apump to the sludge suction ture is built within the tank at the time ofthe member or tube in order to pump out the sludge tanks installation.without affecting the liquid contents of the With the fo i n other je sin view tank. ,The wide area of the suction member 35 w ch Will pp asthe description p ed assuring the even slow flow of the sludge from theinvention resides in the combination and th tank bottom.
